I started at Nintendo of America, but the development groups for everything I worked on there were in Japan.

Also I worked at an outsource testing lab that received projects from all over the US and the world and some were just down the street. Mostly I did video card and OS compatibility testing there, but I did a little of everything.

I worked on Age of Empires III, but the devs were in Texas and I worked in Redmond, WA. I did get direct emails from the devs though, instead of having layers of managerment in between us. I am in the credits for a few games published by Microsoft Game Studios.

At my current job devs walk over and ask me to repro things sometimes. And I can ask them questions directily about what the code is doing or how the game should look.
